Now that the Doctor Who Christmas special, "The Husbands of River Song," has come and gone, fans of the long-running British science fiction television show will have to wait quite awhile before the tenth series arrives in late 2016. The search for a new companion is on, but that's not the only cast member who could need replacing. That's according to the Twelfth Doctor himself, Peter Capaldi, who told the Telegraph that his third year playing the character might be his last:

"This could be my final year. I love Doctor Who but it can be quite an insular world and I do want to do other things. There will come a time when this is over. But I knew that when I started. I was thinking about my regeneration scene from the outset. That's my terrible melancholic nature. When you accept the job you know there'll come a day, inevitably, when you'll be saying goodbye."

"Every Doctor should be different from the last one. If you want exclusively young, sexy guys, to me that's not Doctor Who. You want occasional ones like that - but then some other eccentrics. I always think that if you're Doctor Who, somebody somewhere's going to love you. That's comfort. But if people don't like me there'll be another one along in a minute. It's only Doctor Who - and I say that with the greatest of respect and affection."
